From Bison To Cattle: The Ecology Of The Southern Plains 1500-1750, Jenni Tifft-Ochoa

Calvert Undergraduate Research Awards

Bison made their home on the Southern Plains for millennia. However, their migratory patterns began to shift in the 17th and 18th centuries. My research investigated what caused this drastic shift and how it had far reaching effects on the ecology of the Southern Plains. Using archives from two prominent Catholic priests, I began to piece together why the bison left the Southern Plains. Rather than focus on the Europeans as the main players, I instead focused on the Indigenous peoples, the animals, and the land as the centralized actors in this project. I discovered that the introduction …

Three Methodological Innovations In Race And Ethnicity Research, Jeffrey Napierala Jan 2018

Three Methodological Innovations In Race And Ethnicity Research, Jeffrey Napierala

Legacy Theses & Dissertations (2009 - 2024)

This dissertation examines topics related to racial and ethnic diversity through three essays. Each essay takes a new perspective on a current issue in the literature and utilizes a unique statistical methodology to address that issue. The first essay uses the Monte Carlo Simulation Method to develop a measure of segregation for the ACS and uses it to assess whether the ACS is useful for measuring segregation in places with different sizes. The second essay considers whether a relatively unexplored factor, genetics, is correlated with migration. This perspective broadens our understanding of why migration occurs and is perpetuated over time. …
